Having thus described my invention, What I claim as new, and desire to secure by Letters Patent, is

1. The combination with the draw-bar having the projections at top and bottom, the capplates united thereto by a through-bolt and having another bolt-opening passing therethrough, the forward ends of said cap-plates being formed on a radius with said last-mentioned bolt-hole as a center, of a yoke embracing said cap-plates and having its forward ends fitted to said curved surfaces, a through-bolt passing through said last-mentioned aperture and the yoke to form a pivotal connection, and thimbles or ferrules proj ecting outwardly from the cap-plates and surrounding the bolt; substantially as described.

2. The combination with a draw-bar having projections at top and bottom at the rear end, cap-plates surrounding said projections and secured in place by a through-bolt having its ends or heads made flush with the outer faces of the cap-plates, the forward ends of said cap-plates being formed on a radius with a second bolt-hole as a center and a bolt passing through said last-mention ed hole, of thimbles independent of said cap-plates held in position by said bolt, and a yoke having its forward ends hooked and curved to engage the forward ends of the cap-plates, said yoke being retained in position by the cap-plates, thimbles and through-bolts; substantially as described.
